DealAngel, hotel find engine, has launched a beta version of the DealAngel API. Traditionally, DealAngel provided a user-facing platform that allowed individuals to use its engine to hunt the best hotel rates. With the API, DealAngel hopes to serve as the underlying knowledge that drives 3rd party sites and apps that provide hotel search services.

Airbnb's CEO, Brian Chesky, hinted that Airbnb may soon open an API for third party integration. Chesky envisions the company shifting from a marketplace to a travel platform upon which third parties can plug into. While no specifics were given, Chesky suggested that lack of an API is a hole.
